1986 GMC C10- Square Foundation

A Resto-Mod Squarebody Built by Family and Friends

Focus on the simple fact that working on your truck with your friends and family truly is what brings the most satisfaction. Well, next to cruising the completed truck down the road and into a show, of course. Jason Mattison out of Northport, Alabama, has been involved in the custom-truck scene for a long time. Chances are good he has learned what works and what doesn’t. Jason got his start, as many of us did, due to his father Danny. His path of past builds also reflects a common timeline in the truck world. One of Jason’s first customs was a mini truck in the form of an S-10 Blazer, followed by a custom fullsize GMC Sierra, and now, a classic truck, his 1986 GMC.

Danny picked up the truck a few years ago for less than a couple grand and built it in a resto-mod style with the help of his father, father-in-law, and close friends. Many of the NOS restoration parts the truck needed came from his father and M&M Classic Chevy & Rod Parts. The truck began its new life at Terry Tyner’s shop (Jason’s father-in-law). They had a lot of help from Chad Skelton of Skelton Auto Parts on much of the fabrication needed to get the truck laying frame on 22-inch Raceline billet wheels. The change in altitude came courtesy of a Porterbuilt front Dropmember, Air Lift air bags, and a rear two-link setup.

Jason also got last-minute parts from Chad. Hunter Skelton and Jason Landers provided motivation and a couple hands to get the truck in top-notch shape to roll out to the shows. With the fabrication and restoration taken care of, a 1991 Chevrolet 350 motor was dressed and dropped into the engine bay, saddled by a set of custom wheel tubs. Finishing off the build was a two-tone paint scheme that highlighted the sharp and unmistakable bodyline. Jason Hughes laid down the deep black and bright white paint that was split with a silver highlight. The truck was built to drive and hit up shows, and the bed floor was raised and a custom composite wood bed floor installed for durability when luggage, chairs, and coolers are loaded up for a cruise.
The objective of the build was to create a clean and refined custom that kept the original touches of a classic truck. It couldn’t have been completed without the help of friends and family. Jason successfully pulled off what many people can’t—the function of a daily driver with the fit and finish of a full-blown show truck.
